EVALUATION KIT AVAILABLE

MAX4249–MAX4257

UCSP, Single-Supply, Low-Noise,

Low-Distortion, Rail-to-Rail Op Amps

General Description

The MAX4249–MAX4257 low-noise, low-distortion oper-

ational amplifiers offer rail-to-rail outputs and single-

supply operation down to 2.4V. They draw 400µA of

quiescent supply current per amplifier while featuring

ultra-low distortion (0.0002% THD), as well as low input

voltage-noise density (7.9nV/!Hz) and low input

current-noise density (0.5fA/!Hz). These features make

the devices an ideal choice for portable/battery-powered

applications that require low distortion and/or low noise.

For additional power conservation, the MAX4249/

MAX4251/MAX4253/MAX4256 offer a low-power shut-

down mode that reduces supply current to 0.5µA and

puts the amplifiers’ outputs into a high-impedance

state. The MAX4249-MAX4257’s outputs swing rail-to-

rail and their input common-mode voltage range

includes ground. The MAX4250–MAX4254 are unity-

gain stable with a gain-bandwidth product of 3MHz.

The MAX4249/MAX4255/MAX4256/MAX4257 are inter-

nally compensated for gains of 10V/V or greater with a

gain-bandwidth product of 22MHz. The single MAX4250/

MAX4255 are available in space-saving 5-pin SOT23

packages. The MAX4252 is available in an 8-bump chip-

scale package (UCSP™) and the MAX4253 is available in

a 10-bump UCSP. The MAX4250AAUK comes in a 5-pin

SOT23 package and is specified for operation over the

automotive (-40°C to +125°C) temperature range.
